Because during the Chongzhen period, the navy's bird boats became larger, and the eight oars on both sides of the ship were eliminated, leaving only two large oars at the stern.

Therefore, when heading up the Yellow River, the speed cannot be faster even if the wind is following.

The navy also specifically measured that under favorable wind conditions on the Shuo River, the bird boat could travel about thirty miles in half an hour [with a speed of about 8 knots].

This speed is already the speed limit.

If there is no wind, the speed will be very slow just by rocking the oar.

In this way, naval warships will be exposed to the muzzles of Jiannu Hongyi cannon for a long time.

At that moment, Chongzhen ordered Zheng Sen: "Zheng Sen, didn't you prepare the navy's three-color lantern? Hurry up and send a signal to the navy, asking them to retreat to a safe distance and stop forcing their way in."

Zheng Sen quickly led two other scholars to hang up the three-color lanterns.

Seeing the three-color lantern hanging on the ninth peak, the naval warship immediately turned around and retreated.

But it took time to turn around, and for a while there was still no way to get rid of the threat of Jiannu and Hongyi cannons, so the sound of cannons on the river was still rumbling and the flames were shooting into the sky, and warships were hit by cannons from time to time.

The Ming Navy navy really suffered a big loss this time.

At least ten ships were lost.

…

Duduo was also awakened by the sound of cannons and hurriedly put on his clothes and stood up.

Soon, He Luohui, Wa Xing'a and other generals with white flags arrived one after another.

Wa Xing'a was seriously injured in the battle of Yunlong Mountain. After several months of recovery, his injuries finally recovered. In the past few days, he has been shouting for revenge and threatening to attack Yunlong Mountain again.

Naturally, Duduo ignored him. Why should he seek revenge?

I suffered such a big loss in Shanyang and did not want to take revenge.

Duduo finally understood that the Ming army was still very powerful in defending the city.

Soon, Shi Tu came to report: "Master, the navy of the Ming Army has arrived."

"Has the Ming navy arrived?" Duduo asked with a calm expression, "How is it? Have you stopped them?"

"Master, don't worry." Shi Tu chuckled and said, "I just went to the river to take a look. The fort we built is very strong. Ming Gou's navy warships can't do anything to us. This cannon shot just now

During the battle, our forts and red-coated cannons were unscathed, but Ming Gou's navy warships were sunk by us, and then they retreated in disgrace."

"Okay!" Duduo said happily, "It seems that Hong Chengchou's method is still effective. Even if there is the Yellow River and even if Ming Dog has the advantage of naval warships, he still can't enter the encirclement, and he can't even think of sending a grain of food in.

"

While he was talking, the white fish belly appeared in the east, and then a fast horse galloped over.

"Report..." Still far away, the messenger on horseback shouted loudly, "The army of the Imperial Father and the Regent has arrived fifteen miles away, and Prince Yu will go to greet it immediately!"

After all, they were brothers, so Dorgon only asked Duduo to pick him up alone.

The other county kings like Luo Luohun, Luck Dehun, and Gurma Hui, Beilebeizi, did not have this opportunity.

"Brother Fourteen actually marched all night?" Duduo's expression condensed and he shouted immediately, "Wa Xing, please order all the Ba Yala with the white flag to follow me to protect the frame."

"Hey!" Vasinga agreed loudly.

Soon, Duduo left the camp with Ba Ya La with a white flag.

At this time, the sky was gradually getting brighter, and you could clearly see that outside the big camp with white flags, short green shoots were already growing in the ground. These were newly planted spring wheat.

By the way, Jiannu is almost out of food.

The freshly planted spring wheat will definitely not be enough to provide military rations for the Jiannu slaves.

Therefore, for the next three to four months, we will have to rely on supplies from Beijing.

[Note: The growth period of spring wheat is about 100 days, sowing in May and harvesting in September]

Dorgon led 30 Niulu and 9,080 bannermen with yellow flags, plus 20,000 newly recruited Han troops, escorting 300,000 shi of military rations southward along the canal, taking the waterway all the way to Yanzhou Prefecture.

However, after entering the Taizhuang Gate fifteen miles north of Xia Town, Dorgon decisively ordered the navy to return, and then asked hundreds of thousands of soldiers to push chicken carts and wheelbarrows southward around Xia Town overnight.

…

Seeing the endless line of torches of Jiannu, especially the hundreds of thousands of chicken carts and wheelbarrows pushed by the army soldiers, the general officers of the ten towns under Huang Degong were eager to try, and they all clamored to take advantage of the night.

Launch a sneak attack to rob the slaves' military rations, and even if they can't grab the food, they will burn it.

To be honest, the generals like Huang Shi'an and Tian Xiong were a little confused.

In last year's great victory at Xia Town, they defeated the Xianghuang Banner, which was said to be the most powerful among the Eight Banners of Jiannu, so some of them didn't take Jiannu seriously.

But Huang Degong's mind was still very clear.

Although there was a big victory in Xia Town last year, it was just Jiannu's partial attack, and the fact that he was able to win at that time had a lot to do with Jiannu's carelessness in underestimating the enemy. If Jiannu hadn't underestimated the enemy so much, he definitely wouldn't have been able to win.

And it was still a defensive battle. If it were a field battle, the Ming army would basically die.

Besides, before Jiannu went south, Chongzhen also specifically told him to just guard Xia Town and not to worry about other things. He was strictly prohibited from sending troops without permission unless he had his will.

At that moment, Huang Degong said in a deep voice: "This is my general's order. Anyone who dares to go into battle without authorization will be executed immediately!"

The news about Huang Degong's general soon spread throughout the army, and the generals of the ten towns under his command could only give up their thoughts.

At this time, Yang Ponu, who had been promoted to commander-in-chief, suddenly said: "Master Hou, do you remember that the Holy Master said that the total number of Jiannu soldiers was only a few hundred thousand, right? There are already more than 200,000 Jiannu troops outside Xuzhou City. Why?

Now there are so many Jiannu slaves here again? This queue can’t be seen to the end at a glance, there must be hundreds of thousands of people at least, right?”

"At least 150,000!" Huang Degong made an accurate estimate.

Then he added: "However, these are not real slaves who were built as slaves. They are all wrapped up with the army."

Yang Ponu said: "Master Marquis, you can't just follow the army and serve as soldiers, right? There must be real slaves, right? Calculating half of them, how many real slaves have been transferred? Then isn't the city of Beijing empty?"

"What do you mean?" Huang Degong suddenly turned around and stared at Yang Ponu.

"Uh, ah?" Huang Degong's reaction shocked Yang Ponu and said hurriedly, "It's not interesting, Mr. Marquis, I just want to say that Jiannu is really brave and he is not afraid of us sneaking into his lair.

.”

Yang Ponu really said it casually, but Huang Degong couldn't calm down after hearing it.

Yes, if Jiannu really mobilized all his troops to besiege Xuzhou and confront the Holy Emperor, wouldn't Beijing be empty? What if at this time he led the ten-town frontier army and marched northward at starry night?

Thinking of this, Huang Degong could no longer calm down.

At that moment, Huang Degong said to Yang Ponu: "Yang Ponu, do you dare to go to Xuzhou?"

"Why don't you dare?" Yang Ponu said, "Although Jiannu has completely surrounded Xuzhou City, and there are still night and day ambushes lurking within fifty miles around, but if I want to enter Xuzhou City, it is a piece of cake.

dish."

"Okay!" Huang Degong waved and said, "Come here."

Huang Degong whispered a few words into Yang Ponu's ear.

Yang Ponu immediately bowed his head and said: "I'll accept your order!"

Then he turned around and left quickly.

…

In fact, this is really Dorgon's plan to lure the enemy.

In order to lure the Ming army to attack, Dorgon even transferred the bannermen with yellow flags.

Of course, if the Ming army really comes out, they will find that the coated slaves pushing the chicken cart and the wheelbarrow are not the real coated slaves, but the flag men with yellow flags pretending to be.

Seeing that the Ming army was unmoved, Dorgon sighed: "It's a pity that the Ming army refused to come out."

"Master, this is actually an expected result." Hong Chengchou comforted Dorgon and said, "The Ming army has completely lost the courage to fight in the field since the Songshan battle. It has not recovered yet, but it is precisely because the Ming army lacks the courage to fight in the field.

, our Qing soldiers were able to concentrate their forces to surround Xuzhou City, otherwise once the Ming troops from Shandong, Xiazhen, Pizhou and even Huai'an moved north, Beizhi and even Beijing would face a huge threat, and we would be in trouble."

"So, it's best to eradicate the Ming army in Xia Town first. The Ming army here will always be a threat."

Dorgon frowned and said: "Besides, if we don't take Xia Town, the canal will not be opened. The navy's canals can only go to Taizhuang Lock. Next, they will only rely on chicken buses and wheelbarrows for transportation. This time

There will be no problem if there are wrappings with the army, but there will be no wrappings with the army the next time we transport food, so we will have to make an extra trip then."

This time when he went south, Dorgon also brought over 150,000 pieces of clothing.

These 150,000 coats of clothing came specifically to Xuzhou and Guide Prefecture to farm.

In order to win the Xuzhou Battle, Dorgon really went all out. Not only did he transfer almost all the troops of the Qing Dynasty to the Xuzhou battlefield, but almost all of the more than 200,000 soldiers were also transferred to Xuzhou.

This is really an effort of the whole country to fight to the death with the Ming Dynasty.

From this point, we can also see that the national power of Jiannu was actually very weak.

Fifty years have passed since Lao Nu raised his troops, but when Jian Nu encountered a decisive battle, he still had to use the entire country's troops to have a chance of winning.

The Battle of Saarhu was like this.

The same goes for the Song Jin War.

The battle at Shanhaiguan is still the same.

It was still the same when it came to the Xuzhou War.
